YJ-425Y semi-automatic hydraulic pipe cutting machine maintenance instructions

YJ-425Y metal circular saw pipe cutting machine is a sawing machine that can choose angle and saw without cutting edge. It can cut all kinds of stainless steel, solid bar and other metal materials, especially sawing various thick-walled pipes. It is ideal, except for the sawing, by hand according to the required length (limitable) feeding, the other workpieces are quickly clamped, the speed-adjusting cutting saw, the cutting back, the clamp release are automatically controlled and the sequence is continuously used. It.

The machine has the characteristics of simple operation, low noise, no pollution, good sawing quality, basically no burr inside and outside the slit, high production efficiency, and can be inclined at various angles.

The machine is small in size, and the position of the workpiece raw material is unchanged when chamfering, and the occupied space position is small. Machine dimensions: 1300mm*1000mm*1900mm

1. Oil replacement

In the first 15 days, the second time should be replaced within 90 days, and then every 180 days. When the replacement, the drain port will be opened to leak the old oil, and then the plug will be locked back to the original position to open the oil. Inject 460# hyperbolic gear oil into the mouth and observe it from the oil window. Add to the half of the oil window. If the oil is too small, the gear wear speed will increase. Too much will increase the motor resistance and waste the oil.

2. Slide to the oil section

The slide oil contains the manual oiler and the slide oil of the main clamp, which acts on the lubrication when the head is up and down.

3. Spindle bearing clearance elimination

After the machine is in normal operation for a period of time, the two tapered roller bearings on the main shaft have a slight gap, which will cause the saw blade to sway, which will not only reduce the sawing precision, but also may cause the saw blade to rupture. The saw blade swing must be checked frequently. . When checking, turn off the main power of the machine and shake the saw blade upwards and downwards with your hands. If there is shaking, you need to eliminate the bearing clearance by relaxing (Fig. 1.3-9) and locking it to the saw blade without swinging. The degree can be, and finally the lock nut is locked.

4. Replacement of the saw blade

If the saw blade is not sharp after using for a period of time, it must be replaced. When replacing, please turn off the main power supply and lock the saw blade clockwise. Screw, remove the saw blade lock washer, then replace the new saw blade, pay attention to the sawtooth rotation. The direction should be consistent with the steering of the spindle, otherwise it will not be cut. After the device is finished, return to the original state according to the reverse procedure and start the machine. The inspection is normal, and the saw blade can be sawed without swinging.
